问题是我无法在页面上保留textarea值 从数据库中获取textarea的值,但不能保留其先前的值。
HTML:
<textarea class="form-control" name="a" rows="3"> </textarea>
PHP:
$_SESSION['b']['page3']=$_POST; FETCHING VALUE IN SESSION
$query = "INSERT INTO `a`(`textarea`) values('".$page3['B']."')";
// inserted properly textarea value in database
// now fetching textarea value
$query = "SELECT * FROM `a` WHERE `id` = '1'";
$data = mysqli_query($conn,$query);
$result =mysqli_fetch_array($data,MYSQLI_ASSOC);
$textarea1 = $result['textarea'];
现在想要保留textarea值:
<textarea class="form-control" rows="3" name="texta">
//CODE FOR RETAINING TEXTAREA VALUE
<?php if(!empty($_SESSION['texta']))echo $_SESSION['texta']; ?>
</textarea>
答案 0 :(得分:2)
假设,
<强> HTML:强>
<form action="" method="POST">
..
<textarea class="form-control" name="a" rows="3"> </textarea>
..
</form>
<强> PHP:强>
<?php
// Setting textarea value in session if not empty
if(!empty($_POST['a']))
{
$_SESSION['texta'] = $_POST['a'];
}
// Inserting to database
..
..
再次HTML:
<textarea class="form-control" rows="3" name="texta">
<?php
if(!empty($_SESSION['texta']))
echo $_SESSION['texta'];
?>
</textarea>
